【摘要】：将纳米氮化钛颗粒分散到水基础液中,加入适量的分散剂,采用两步法可制备出具有良好分散稳定的水基纳米氮化钛流体。在此基础上,采用单一变量法,用M-200磨损试验机研究了这种纳米流体对钢环的磨损性能,并对其摩擦润滑机理进行了分析。结果表明:摩擦系数与磨损量随负荷的增加表现出先减小后增大的趋势,并且当质量分数为1%的PVP与CTMAB混合液作为分散剂、粒径为20nm且质量分数为1%的氮化钛颗粒、分散介质为去离子水时表现出最佳的润滑性能。
[Abstract]:The nanometer titanium nitride particles were dispersed into the water base solution, and the proper amount of dispersant was added to the water base solution. The water based nano-titanium nitride fluid with good dispersion and stability could be prepared by two-step method. On the basis of this, a single variable method was adopted. The wear performance of the nano-fluid to steel ring was studied by M-200 wear tester, and the friction lubrication mechanism was analyzed. The results show that the friction coefficient and wear quantity decrease first and then increase with the increase of load. When the mixture of PVP and CTMAB with mass fraction of 1% is used as dispersant and the particle size is 20 nm and the mass fraction of titanium nitride is 1%, the dispersion medium is deionized water, which shows the best lubricating performance.
